| 中文摘要: |
| 通过光催化将二氧化碳(CO2)还原为可持续的绿色太阳能燃料是同时解决环境问题和能源危机的极具前景的方案. 尽管迄今为止已经进行了广泛的研究, 但实现高转化率、 高选择性和高稳定性的光催化二氧化碳还原仍有许多障碍. 如将水作为电子供体而非牺牲试剂, 能够使反应的吉布斯自由能变ΔG>0, 这对于真正实现理想化的人工光合作用至关重要, 但同时也会为光催化还原CO2体系带来更多的挑战. 我们首先简要介绍了光催化还原CO2的机理与挑战, 而后根据目前光催化还原CO2在无牺牲剂体系中出现的问题总结了对应的策略以及最新的研究进展, 包括能带结构的调整、 助催化剂的负载、 异质结的构建、 MOFs与COFs材料的设计等方面, 最后对目前仍未解决的问题以及未来实现工业化应用的阻碍进行了总结. |

| Photocatalytic reduction of carbon dioxide into sustainable green solar fuel is a promising solution to both environmental problems and energy crises. Despite extensive research to date, there are still many obstacles to achieving efficient, selective and stable CO2 reduction. Furthermore, the use of water as an electron donor rather than a sacrificial reagent in order to achieve ΔG>0 of the reaction is essential for ideal artificial 'photosynthesis', but it also presents many challenges for photocatalytic reduction of CO2 systems. In this review, we first briefly introduce the mechanism and challenges of photocatalytic reduction of CO2, and then we summarize the corresponding strategies and the latest research progress according to the current problems of photocatalytic reduction of CO2 without sacrificial reagent, such as the adjustment of band structure, the loading of cocatalysts, the construction of heterojunctions, the design of MOFs and COFs materials, etc. At last, the unsolved problems and the obstacles to industrial application in the future are summarized. |
